[COMMON] Enable importing custom certificates to truststore using certInitializer

ONAP deployments may require the use of custom certificates. Instead of
manually adding certificates to the truststore file, users can now add
their .pem certificates under certInitializer/resources and have them
imported automatically by an init container. The updated truststore can
then be mounted to a component by providing a truststoreMountpath.
